Running KDE Neon 6.3.5, Nvidia 570.144 proprietary drivers, an RTX 4070S.

I'm not too sure just when this started, but I no longer have the option to enable Nvidia Frame Gen, I only have the option for AMD FSR3 Frame Generation - Which honestly isn't as good.

I think the issue may have presented itself when SteamDeck=1 %command% became a hard pre requisite to run the game?

Is anyone else seeing the same behavior, or is it just me?

Steam launch options below:

gamemoderun mangohud LD_PRELOAD="" SteamDeck=1 %command% -PSOCompileMode=1

try adding PROTON_FORCE_NVAPI=1 to the launch options

Thanks for the response, I actually figured it out.

If I run GE-Proton9-27, Frame Gen works fine. If I use anything newer than GE-Proton9-27, I get the DLSS option, but only AMD FSR3 Frame Generation - It seems like a regression with recent Proton builds, as it also happens under Steam Proton 10.

I might try running a newer version of Proton when I get time and see if the launch option you've quoted resolves the issue, right now I'm just glad to have Frame Gen working again.
